Problems solved by technology

[0005] At present, the international solid oxide electrolyte direct carbon fuel cell research mostly stays in the single-cell experiment stage, and the practical application still faces the problem of feeding solid carbon fuel on the anode surface, especially when the anode surface is in direct contact with the anode surface after a period of reaction. The problem of continuous feeding when the solid carbon fuel has been completely reacted
At the same time, the direct carbon fuel cell with fixed bed structure is not conducive to the occurrence of non-contact mechanism reaction between carbon and anode, and is also not conducive to internal heat and mass transfer. The circulating fluidized bed direct carbon fuel cell proposed by Stanford University in the United States can solve the problem to a certain extent. It is also conducive to the occurrence of non-contact mechanism reaction between carbon and anode, but this design is not conducive to the occurrence of direct contact mechanism reaction between carbon and anode. At the same time, the structure is complex and the battery wears a lot

Description

technical field [0001] The invention relates to a buried tube type bubbling bed direct carbon fuel cell, which belongs to the technical field of direct carbon fuel cell devices. Background technique [0002] At present, fuel cell technology has become one of the research hotspots at home and abroad because of its remarkable advantages. Direct Carbon Fuel Cell (DirectCarbon Fuel Cell, DCFC) is also a kind of fuel cell. Unlike batteries that use gas or liquid fuel, DCFC uses solid carbon as fuel. Its unique advantages are: the theoretical efficiency of the battery is higher; the use of solid carbon fuel , save the gasification link, and at the same time, the solid carbon fuel has small volume, high calorific value, convenient transportation and storage, is not easy to leak and explode, and reduces the requirements for battery sealing, especially high-temperature sealing; Coal is obtained through simple processing, and the fuel is easier and more widely obtained than hydrogen ...
